In Figs; 3 and 1 1 show a form similar to that of Fig. 2, except that. the. superl'ieater tubes are arranged in separated groups. 14" and 15", as shown in Fig 4, the boxes 1G and 17" extending hetweeii the 'nLe-an'r cireulutur tubes and the \vuter-circu-latortubes of the two drums-x In this cause thcwater groups-of superheatiug tubes.

are matted with similar numeralswith the letter aupplied,u11 l in 1 igs. 3 nnd i'similar 1 parts are also marked with snmlurnumeruls 105 wit-lithe letter I) applied. The advent ages of my invention result from the arranging of the superheute'r with its pipes extending on both sides of the particirculuters 12 extend in groups between the tion or bafile between theban'ks o-ii atnbeshllp In this way large superheating surface may be obtained while the boiler need not be enlarged as to floor s Jace or height. The U- sha ed tubes are u advanta e in this articu ar location as they stradd e the partition and provide superheating surface above it.

One or more mud drums may be em loycd, the tubes maybe curved or straight an either vertical or inclined, more than two banks of tubes may be used and the form of superheater may be varied without departing from my invention.

1. A superheater boiler having two or more transverse steam and water. drums connected by banks of tubes to a mud drum or drums, a battle or partition between the banks of tubes and a super-heater having tubes extending on both sides of the partition between it and the water tubes said superheater being independent of the boiler drums; substantially as described.

2. A superheater boiler having two or more transverse steam and water drums connected by banks of tubes to a mud drum or drums, a ballie or partition between the banks. of tubes and a superheater having U-shaped tubes extending on both sides of the partition between it and thewater tubes; substantially as described.

3. A superheater boiler having two banks of tubes connecting transverse upper and 'lower drums, a partition between the banks and a superlreater having U-shaped tubes with their legs directed downwardly and straddling the partition; substantially as described.

4. A superheater boiler having transverse steam and water drums connected by banks of tubes to transverse'connected drums, a partition between the banks of tubes, :1 s11 perheater having tubes-on each side of the partition-between it and the water tubes and of tubes to transverse connected mu projecting upwardly between the steam and water drums and water circulating tubes connecting the steam and water drums and extendin across the upper ends of the superheater' tu es; substantlally as described.

5. A superheater boiler having transverse banks drums, water circulators between the steam and Water drums, and a superheater consisting of U-shaped tubes with their legs at opposite steam and water drums connected b sides of the partition and their upper por-' tions extending between the water circulators; substantially as described.

6. A su erheater boiler of the transversedrum, mu tip1e-bank, serial pass ty'p'e having a, vertical baffle dividing the space between adjacent banks into an up-pass and a down-pass, a su erheater having at least a portion thereof ocated above the ballie be tween two of the banks of tubes, a part of the superheater being in the up-pass and another part of the superheater being in the down-pass, substantially as described.

7. A superheater boiler of the transverse-- drum, multiple-bank, seria1-pass type, having an upwarally-extending battle or partition between two of the banks of tubes dividing the space into an up-pass and a down-pass, and a su n-rheater located between the banks of tubes and including boxes and U-shaped tubes connected thereto, at least a portion of the superheater being above the baflle with a part of the superheater'in the lip-pass and another part in the downpass, substantially as described.

In testimony whereof, I have hereunto set my hand.
